Answer 1

I don't really see all the point of your request.

(@^http[s]?://[^/] /[^/] ?(/?(index/[^/])?)?$@)

This will resolve your 1,2,3 but not the 4,5,6

This regex might work for you:

(/pressrelease)(/index/\d+)?/?$

Here isn't a way to cheat around it

Answer 4

If you wanted to capture the whole string

(http:\/\/.*pressrelease(()|(\/)|(\/index)|(\/index\/[^\/]*)))$
